help..

Okay I've made and deleted this post multiple times now. I only use this app to keep up with my dates for my period. But I need some help. As of today, I am 13 days late. At first I thought it was just stress so I didn't worry too much. But now I'm 13 days late and my percentage of being pregnant is growing every day. I have not taken a test yet, but will be soon. I had unprotected sex at the end of April during my fertile week according to my app. My boobs have been extremely sore for about 3 weeks now. My sleep is way off, I'm either exhausted or can't sleep. And my appetite is all over the place    What do y'all think?
